      How To Convert a Gatsby Site to a Progressive Web App

      The author selected the Internet Archive to receive a donation as part of the Write for DOnations program.


      Gatsby is a popular framework for turning source material into static HTML files that are ready for instant deployment. Because of this, it is often called a Static Site Generator (SSG). As an SSG, it already has a positive impact on user experience (UX) by turning multiple content sources into an optimized website, but there is another layer available for UX improvement: Progressive Web App capabilities.

      A Progressive Web App, or PWA, is a type of website that goes beyond the usual limits of web capabilities, using newer technology to bridge the gap between your browser and your operating system. PWAs encompass a lot of different features, such as offline browsing, installation support, and newer web APIs. By combining these features, PWAs deliver your users an improved overall browsing experience, as well as the option to use your website like any other application, complete with its own icon and app window.

      Although there is a lot that goes into making an optimal PWA, Gatsby provides tools and support to streamline the process, such as a manifest file plugin (gatsby-plugin-manifest) and an offline plugin (gatsby-plugin-offline). This tutorial will walk you through using these plugins, as well as audit tools like Lighthouse, and by the end you will have learned how to take a Gatsby site and turn it into a fully-functional Progressive Web App.


      Before starting, here are a few things you will need:

      • A local installation of Node.js for running Gatsby and building your site. The installation procedure varies by operating system, but DigitalOcean has guides for Ubuntu 20.04 and macOS, and you can always find the latest release on the official NodeJS download page.
      • Some familiarity with JavaScript, for working in Gatsby. The JavaScript language is an expansive topic, but a good starting spot is our How to Code in JavaScript series.
      • An existing Gatsby project that does not yet have PWA support, but is otherwise functional. For satisfying this requirement and building a new Gatsby project from scratch, you can refer to Step 1 of the How to Set Up Your First Gatsby Website tutorial.
      • (Optional) An icon file for your website. In order to be installable, your PWA will need an icon with an original resolution of at least 512 x 512 pixels. If you do not have an icon in mind, this tutorial will instruct you to download a sample icon in Step 2.

      This tutorial was tested on Node v14.17.2, npm v6.14.13, Gatsby v3.9.0, gatsby-plugin-offline v4.8.0, and gatsby-plugin-manifest v3.8.0.

      Step 1 — Preparing Your Content (Optional)

      As a prerequisite, you already have created a functional Gatsby site that can be built and deployed. However, you might not have any content for your site yet. In this step, you will prepare a sample smart home user guide site to demonstrate what kind of content benefits from PWA features.

      As a smart home user guide is something likely to be visited multiple times by the same user, it makes a great example to showcase the main features of a PWA. The app-like qualities of a PWA, such as installation support and home screen icons, make it accessible on both mobile and desktop devices, and thanks to offline support, even when your home network fails, you or other residents can still access the guide.

      Building off the starter template, you can add a new page for the smart home guide under src/pages. Create a file named src/pages/internet-issues.js, and add the following sample page code:


      import * as React from "react"
      import { Link } from "gatsby"
      import Layout from "../components/layout"
      import Seo from "../components/seo"
      const IndexPage = () => (
          <Seo title="Internet Issues" />
          <h1>Internet Issues - Troubleshooting</h1>
          <p>Having issues connecting to the internet? Here are some things to try in our house.</p>
            <li>Your Device
                <li>Is airplane mode on? Is WiFi enabled?</li>
                <li>Is the device within range of the router or physically connected to the network via ethernet?</li>
                <li>Are you connected to the correct network?</li>
            <br />
            <li>The Router / Modem
                <li>Have you checked the ISPs status page to check for an outage? You can use your smartphone and mobile data to check this.</li>
                <li>Have you tried rebooting the router and/or modem?</li>
                <li>Have you checked to make sure that all physical connections to and from the router and modem are secure?</li>
            <Link to="/">Back to homepage</Link> <br />
      export default IndexPage

      In this page code, you’ve provided troubleshooting instructions to your housemates or guests for when they are having trouble connecting to the internet. You have done so with a bulleted list, providing a link back to the homepage for easier navigation. Since this is a Gatsby project, you’ve created the entire page as a React component, which will nest your list inside a reusable Layout component and return the page as JSX so Gatsby can process it. For an optimized navigational experience, you’ve also used a Link component to link back to the homepage, instead of a regular HTML a tag.

      Make sure to save the file after updating it, and you can go ahead and close it since you won’t need to update it again in this tutorial.

      This page will be accessible at your_domain/internet-issues/, but you will also add a link to it from your homepage to make it easier to get to.

      Open up src/pages/index.js, and add a direct link to the new page within the React component IndexPage, as shown in the following highlighted code:


      import * as React from "react"
      import { Link } from "gatsby"
      import { StaticImage } from "gatsby-plugin-image"
      import Layout from "../components/layout"
      import Seo from "../components/seo"
      const IndexPage = () => (
            <Link to="/internet-issues/">Internet Issues Troubleshooting Page</Link> <br />
            <Link to="/page-2/">Go to page 2</Link> <br />

      Save and close index.js with the added link.

      You’ve now built a brand new page for your smart home user guide and added a link to get to it from your homepage. In the next step, you will be adding a special file known as a manifest file, which instructs web browsers on the specifics of your PWA setup.

      Step 2 — Adding a Manifest File

      The next step is fulfilling one of the core requirements of PWAs by adding a manifest JSON file, manifest.json. The manifest file tells the web browser details about your site and how to display it to the user if it is installed on the users’s OS, specifying details such as what icon to use and how it should be launched. You will use gatsby-plugin-manifest to generate this file by initializing the plugin in your Gatsby config file.

      First, install the Gatsby plugin by running the following command in your Gatsby project directory:

      • npm install gatsby-plugin-manifest

      Next, you will provide some details to the plugin that tell it how you want the PWA to appear and act. You do this by editing the main Gatsby config file that lives in the root of your project directory, gatsby-config.js. Open this file and add the following code:


      module.exports = {
        plugins: [
            resolve: `gatsby-plugin-manifest`,
            options: {
              name: `My Smart-Home Guide`,
              short_name: `SH Guide`,
              description: `Guide for residents of the ABC123 Smart Home`,
              start_url: `/`,
              background_color: `#0a68f0`,
              theme_color: `#0a68f0`,
              display: `standalone`,
              icon: `src/images/pwa-icon.png`,
              icons: [
                  src: `/favicons/pwa-icon-192x192.png`,
                  sizes: `192x192`,
                  type: `image/png`
                  src: `/favicons/pwa-icon-512x512.png`,
                  sizes: `512x512`,
                  type: `image/png`

      Note: If you have started with the gatsby-starter-default template, you will already have some values for this plugin in your config file. In that case, overwrite the existing values with this code.

      There are a lot of values in this file, so here is a quick explanation:

      • name and short_name should correspond with the name of your site and how you want the site to appear to users when installed. short_name appears on the home screen of the user’s device, or other places where space is limited, and name appears everywhere else.
      • description should be text that describes the purpose of your application.
      • start_url is used to suggest to the browser which page should open when the user launches the PWA from their launcher. A value of /, as used here, tells the browser you would like the user to land on your homepage when opening the PWA.
      • background_color and theme_color are both directives to the browser on styling the PWA, and the values should correspond to CSS color strings. background_color is only used while waiting on the actual stylesheet to load, as a placeholder background color, whereas theme_color is potentially used in multiple places outside the PWA, such as surrounding the icon on an Android home screen.
      • display is a special value because it dictates how your entire site acts as a PWA, and, unlike other fields which support hundreds of different combinations, can be one of four possible values: fullscreen, standalone, minimal-ui, or browser. In your config, the value of standalone makes the PWA act like a standalone application outside the standard web browser. In practice, this means that it acts similar to a native application—it gets its own launcher icon, application window, and the URL address bar is hidden.
      • icon is not one of the standard manifest fields, but is a special field within the context of gatsby-plugin-manifest. By using this property, and providing a path to a file that meets the minimum requirements (at least 512x512 pixels, square), the Gatsby plugin will automatically transform the image into a site favicon, as well as inject into the manifest as the required icons manifest property. By specifying icons with an array of filenames, sizes, and image types, you are invoking the Hybrid Mode Configuration of the manifest plugin. This takes your single source icon file and transforms it into the filenames and sizes specified. This is not strictly necessary, but it avoids any possible issues with deployments in environments like Apache, which don’t work with the default /icons directory.

      Make sure to save the config file with your changes, but keep it open for the next step, where you will be adding another Gatsby plugin and configuring offline support.

      In the manifest values, the path used for icon was src/images/pwa-icon.png, but you still need to place an image file at that location before it will work. If you have a square image file that is at least 512 x 512 pixels, you can copy it to that path. Otherwise, you can use a pre-formatted image file selected for this tutorial. To use the tutorial icon file, either download the sample icon file for this tutorial and save it at src/images/pwa-icon.png, or if you prefer the command line, use cURL from your project root directory:

      • curl -o ./src/images/pwa-icon.png

      This will download the image to the correct part of your Gatsby application. This is the only image file you’ll need; Gatsby will automatically generate the 192x192 version.

      You have now configured your Gatsby project to serve a manifest JSON file with the correct values, which is a required part of enabling PWA capabilities. In the next step, you will be addressing another requirement of PWAs, offline support, by adding the feature via a service worker plugin, gatsby-plugin-offline.

      Step 3 — Adding Offline Support with Service Workers

      Another key component of PWAs is offline support, which you will implement with a piece of web technology known as a service worker. A service worker is essentially a bundle of JavaScript code that runs separately from all the code tied to the UI of the page you are on. This isolated code is also granted special privileges, such as the ability to alter the behavior of network requests, which is critical for implementing offline support. In this step, you will set up a robust service worker through the gatsby-plugin-offline plugin, configured through your Gatsby config file.

      Start by installing the gatsby-plugin-offline package and adding it to your dependencies. You can do so with:

      • npm install gatsby-plugin-offline

      Next, load the plugin through the Gatsby config, the same gatsby-config.js edited in the previous step:


      module.exports = {
        plugins: [
            resolve: `gatsby-plugin-manifest`,
            options: {

      Make sure to save the configuration file after adding the new plugin.

      Warning: Both the docs for gatsby-plugin-manifest and for gatsby-plugin-offline specify that gatsby-plugin-offline should always come after gatsby-plugin-manifest in the configuration array, as shown in this code snippet. This ensures that the manifest file itself can be cached.

      At this point, you’ve both added offline support and created a manifest file for your app. Next, this tutorial will explain the third necessary part of a PWA: having a secure context.

      Step 4 — Providing a Secure Context

      The last of the three basic minimum requirements for any PWA is that it run in a secure context. A secure context refers to a web environment in which certain baseline standards are met for authentication and security, and most often is referring to content served over HTTPS.

      A secure context can be achieved in many ways. Because of this, this tutorial will describe a few different strategies to get a secure context, then move forward with testing your Gatsby site locally.

      If you are deploying your Gatsby project through a static host, such as DigitalOcean’s App Platform, then it is likely that HTTPS is supported out of the box, with no setup required. For more information on deploying your app on App Platform, check out the How To Deploy a Gatsby Application to DigitalOcean App Platform tutorial.

      If you are deploying on a server that does not automatically provide HTTPS, but you have SSH access, you can use Let’s Encrypt to obtain and install a free TLS/SSL certificate. For example, if you are using Apache with Ubuntu 20.04, you can follow How To Secure Apache with Let’s Encrypt on Ubuntu 20.04 to use Certbot to handle this process. If you are deploying to a shared host, you will want to check their specific documentation pages for if, and how, SSL certificate installation might be available.

      For local testing, you don’t have to deal with obtaining or installing an SSL certificate. This is because most modern browsers treat localhost sites as a secure context, even without a TLS/SSL certificate installed or HTTPS protocol.

      You now have successfully added PWA support to your Gatsby project by meeting the three baseline criteria: HTTPS (or a localhost secure context), a manifest file, and a service worker. The next step is to test and verify that it shows up correctly, with PWA features enabled.

      Step 5 — Running Local Tests

      In this step, you will run some local tests to make sure your PWA functionality is working properly. This is an initial testing step before using the Lighthouse tool for a more comprehensive audit.

      To locally test your Gatsby site’s functionality as a PWA, build it and then serve the generated build directory:

      • npm run build
      • npm run serve

      Once it is ready, you will see the following:


      You can now view gatsby-starter-default in the browser. ⠀ http://localhost:9000/

      You can now visit that URL in your web browser, and if the browser supports PWAs, you will encounter some special additional UI elements. For example, on Chrome desktop, there will be a new button exposed in the address bar that, when clicked, asks if you would like to install the Gatsby site as an app, as shown in the following image:

      Screenshot showing a popup menu, originating from the Chrome desktop address bar, asking if you would like to

      If you want to test your site locally on a smartphone, this is possible with something like Chrome’s remote debugging tool (Android only), or a localhost tunneling service such as ngrok. On mobile, you will encounter the same option to install your site as an app, as shown in the following:

      Screenshot from an Android device, showing a

      This PWA prompt is different for each device, operating system, and browser. Additionally, certain features such as Add to Home Screen might only be available on certain devices. Certain browsers running on specific devices might not support PWAs entirely; check for more information on platform support.

      You have now verified that your Gatsby project can be built and served locally, with your browser successfully detecting that it offers PWA functionality. The next step will be a final check against what you have put together, and using the Lighthouse tool to check if there are areas for improvement.

      Step 6 — Running an Audit with Lighthouse

      At this point, you have a Gatsby site that meets all the core requirements for a PWA: it has HTTPS, a manifest, and a service worker for offline support. However, the concept of a PWA goes beyond any single requirement—it encompasses all of the facets working together, plus adhering to general guidelines. With this in mind, your last step is to use an audit tool to verify that you meet the baseline criteria, as well as gather information on how you can further optimize your Gatsby project to meet PWA best practices.

      There are a few different ways to audit your site as a PWA, but at the moment the gold standard is the Lighthouse Tool. If you have desktop Chrome installed, you can run an audit against your site directly in the web browser DevTools.

      First, navigate to your Gatsby site in Chrome, then open Chrome DevTools by right clicking anywhere on the webpage and selecting Inspect in the right click menu. Next, click the Lighthouse tab under DevTools. If you don’t see it, click the >> label next to the right-most tab to show tabs that are hidden due to size constraints.

      Now, to actually run the report, uncheck everything on the Lighthouse tab except for Progressive Web App, and then hit Generate Report to analyze your site:

      Screenshot showing the Lighthouse tab in desktop Chrome DevTools, with only the Progressive Web App report category checked

      You can also generate this report programmatically, via the Lighthouse Node.js CLI. This command will run the PWA-only audit and then open the report for viewing:

      • npx lighthouse http://localhost:9000 --only-categories=pwa --view

      However, using Lighthouse via CLI does not bypass the need to have Chrome installed; this just makes it easier to automate the process.

      The report generated by Lighthouse tells you a few things, broken down into categories. Some of the most important are:

      • Installable: This is the most important category, and addresses whether or not your site meets the three baseline criteria for being an installable PWA—HTTPS, manifest files, and a service worker.
      • PWA Optimized: These are things that you should be doing for an optimal PWA user experience, but aren’t strictly required for your PWA to be functional. Think of these as best-practice suggestions. Some examples of these are creating a custom splash screen to display during mobile app loading, setting a theme color for the address bar, and providing fallback content for when JavaScript is unavailable. If you’d like to look at the full list, check out the official Lighthouse documentation.

      By using the Lighthouse tool to audit your Gatsby PWA, you not only now have a functional PWA, but also have an idea of how it meets PWA requirements and best practices.


      After following these steps, you now have a Gatsby site that can also function as a modern installable Progressive Web App, with strong offline support. You are now providing your users with the best of both worlds: They can browse your site as a normal web page, but they can also use it as they would a native application, with its own launcher icon, display window, and the reliable performance they expect from native applications.

      If you are looking for more ways to deliver the most optimized PWA experience possible, in addition to the Lighthouse PWA audit, Google also has a published a PWA checklist that will help.

      How To Use Python-Markdown to Convert Markdown Text to HTML

      The author selected the COVID-19 Relief Fund to receive a donation as part of the Write for DOnations program.


      Markdown is a markup language commonly used to simplify the process of writing content in an easy-to-read text format, which a software tool or programming library can convert into HTML to display in a browser or another writing program. Because it uses plain-text syntax, Markdown is compatible with any text editor and can convert headings, lists, links, and other components. Bloggers, tutorial authors, and documentation writers use Markdown widely and websites, such as Github, StackOverflow, and The Python Package Index (PyPI), support it.

      You can learn how to use Markdown from the Markdown syntax standard. Alternatively, you can also try a different Markdown implementation in a web editor, like the DigitalOcean Markdown Preview or the StackEdit editor.

      Python-Markdown is a Python library that allows you to convert Markdown text to HTML in various ways. You can extend its functionality using its different extensions that provide additional features. Note however, that the Python-Markdown has a few minor differences with the standard Markdown syntax.

      In this tutorial, you will install the Python-Markdown library, use it to convert Markdown strings to HTML, convert Markdown files to HTML files, and use the Python-Markdown command line interface to convert Markdown to HTML.


      Before you start following this guide, you will need:

      Step 1 — Installing Python-Markdown

      In this step, you will install Python-Markdown and explore one of its functions to convert Markdown strings to HTML in the Python REPL.

      If you haven’t already activated your programming environment, make sure you’re in your project directory (pymark) and use the following command to activate the environment:

      Once you have activated your programming environment, your prompt will now have an env prefix like the following:

      Now you’ll install Python packages and isolate your project code away from the main Python system installation.

      Use pip to install the Python-Markdown library (markdown) by running the following command:

      Once the installation finishes successfully, you can experiment with it in the Python REPL, which you can open by typing the following command:

      You will notice a new prompt with the prefix >>>; you can use this to type in Python code and receive immediate output.

      First you will import the markdown package and use it to convert a piece of Markdown text from Markdown syntax to HTML:

      • import markdown
      • markdown.markdown('#Hi')

      In this code, you import the markdown package you installed earlier. You use the markdown.markdown() function to convert the Markdown text #Hi (with # representing an H1-level header) to its HTML equivalent. If you type the code into the Python REPL, you will receive the following output:



      The HTML output is the equivalent of the #Hi Markdown text.

      You can use triple single quotes (''') to type multi-line Markdown text into the Python REPL like so:

      • import markdown
      • output = markdown.markdown('''
      • # Step 1
      • ## Step 2
      • * item 1
      • * item 2
      • Visit [the tutorials page]( for more tutorials!
      • ''')
      • print(output)

      In this example, you pass an H1 header, an H2 header, two list items, and a paragraph containing a link. You then save the output in a variable called output and print it with the print() Python function.

      You will receive the following output:


      <h1>Step 1</h1> <h2>Step 2</h2> <ul> <li>item 1</li> <li>item 2</li> </ul> <p>Visit <a href="">the tutorials page</a> for more tutorials!</p>

      You’ll notice that the output results in the HTML version of the provided Markdown text.

      Now that you’ve used the markdown package to convert Markdown text to HTML, you will make a small program to read and convert Markdown files to HTML files.

      Step 2 — Creating a Program to Convert Markdown Files to HTML

      In this step, you will create a Python program that reads a Markdown file, converts its contents to HTML using the markdown.markdown() function, and saves the HTML code in a new file.

      First, open a new file called to hold the Markdown text:

      Type the following Markdown text into it:


      # Things to bring
      * Food.
      * Water.
      * Knife.
      * Plates.

      In this file you have an H1 header and four list items.

      Once you’re done, save and close the file.

      Next, open a new file called to hold the code for converting the Markdown file to an HTML file:

      Type the following Python code into it:


      import markdown
      with open('', 'r') as f:
          text =
          html = markdown.markdown(text)
      with open('Picnic.html', 'w') as f:

      Here, you first import the markdown package. You use the open() function to open the file; passing the value 'r' to the mode parameter to signify that Python should open it for reading.

      You save the file object in a variable called f, which you can use to reference the file. Then you read the file and save its contents inside the text variable. After, you convert the text using markdown.markdown(), saving the result in a variable called html.

      With the same pattern, you open a new file called Picnic.html in writing mode ('w')—note that this file does not yet exist—and write the contents of the html variable to the file. This creates and saves the new file on your system. Using the with statement when opening a file guarantees that Python will close it once processing has finished.

      Save and close the file.

      Run the program:

      This creates a new file called Picnic.html in your project directory with the following contents:


      <h1>Things to bring</h1>

      Now that you know how to open and convert Markdown files using the markdown.markdown() function, you can generate Markdown text in Python and convert Markdown files without the need to read them first.

      Step 3 — Generating Markdown from Data and Converting it to HTML

      In this step, you will create a program that generates Markdown text from a Python dictionary, saves it to a Markdown file, and converts the Markdown text to an HTML file using the markdown.markdownFromFile() function.

      Your program will generate a Markdown file called with a list of countries and their top three largest cities. After, the program will convert the generated Markdown text into HTML, then it will save the HTML in a file called cities.html.

      First open a new Python file called

      Then add the following Python code:


      import markdown
      country_cities = {'Japan': ['Tokyo', 'Osaka', 'Nagoya'],
                        'France': ['Paris', 'Marseille', 'Lyon'],
                        'Germany': ['Berlin', 'Hamburg', 'Munich'],

      In this code you first import the Python-Markdown library with import markdown. Then you define a country_cities dictionary containing a few countries as the keys and a list of the largest three cities for each country as the value. This dictionary is an example data structure; you can replace it with fetched data from a web API, a database, or any other data source.

      Next add the following code after your dictionary:


      . . .
      with open('', 'bw+') as f:
          for country, cities in country_cities.items():
              f.write('# {}n'.format(country).encode('utf-8'))
              for city in cities:
                  f.write('* {}n'.format(city).encode('utf-8'))

          markdown.markdownFromFile(input=f, output="cities.html")

      After constructing the dictionary that holds the data, you use the with open(...) as ... syntax to open a file called, which doesn’t exist yet. You open it in binary mode ('b') for writing and reading ('w+'). You use binary mode, because if you pass a string to markdown.markdownFromFile(), it will be interpreted as a path to a readable file on the file system (that is, '/home/'). Also binary mode allows you to avoid issues related to converting characters to a platform-specific representation; this guarantees that the Python program will behave the same way on any platform.

      You then go through the dictionary’s items extracting each key that contains the country’s name and saving it in the country variable. Alongside this, you extract the value that represents the list of the country’s largest cities and save it in the cities variable.

      Inside the first loop, you write the country’s name to the new file in a # Markdown header (the <h1> HTML tag). n is a special character for inserting a new line. You use .encode() because you have opened the file in binary mode. The second for loop iterates through each city and writes its name to the Markdown file as a * list item (the <li> HTML tag).

      After the first loop finishes, you have moved to the end of the file, which means markdown.markdownFromFile() won’t be able to read its contents; therefore, you use to go back to the top of the file. Before passing the f object to markdown.markdownFromFile() as input, to convert it to HTML and save it to a new file called cities.html.

      Once you’re done, save and close the file.

      Run the program:

      This command will generate two files:

      • A Markdown file with the following contents:


      # Japan
      * Tokyo
      * Osaka
      * Nagoya
      # France
      * Paris
      * Marseille
      * Lyon
      # Germany
      * Berlin
      * Hamburg
      * Munich
      • cities.html: An HTML file that contains the result of converting the contents of



      You can also use the function markdown.markdownFromFile() to convert an existing Markdown file. For example, you can convert the file to a file called Picnic-out.html using the following code:

      import markdown
      markdown.markdownFromFile(input="", output="Picnic-out.html")

      You can use the markdown.markdownFromFile() function to directly convert a file, if the file does not need any modification. If you do need to modify the Markdown file, you can read it, then convert it using the method demonstrated in Step 2.

      You’ve converted Markdown text to HTML in Python code, but Python-Markdown also provides a helpful command line interface (CLI) to quickly convert Markdown files to HTML—you’ll review this tool in the next step.

      Step 4 — Using Python-Markdown’s Command Line Interface

      In this step you will use Python-Markdown’s CLI to convert a Markdown file to HTML and print the output, or save it to an HTML file.

      You can run the Python-Markdown command line script using the -m flag supported by Python, which runs a library module as a script. For example, to convert a Markdown file, you can pass it to the markdown command as follows, replacing with the name of the file you want to convert:

      • python -m markdown

      Executing this command will print the HTML code for the Markdown text that’s present in the file.

      For example, to convert the file, run the following command:

      • python -m markdown

      This will print the following output:


      <h1>Things to bring</h1> <ul> <li>Food.</li> <li>Water.</li> <li>Knife.</li> <li>Plates.</li> </ul>

      To save the output to a file called output.html, use the following command:

      • python -m markdown -f output.html

      With this, you’ve now used the markdown command line interface to convert a Markdown file to HTML.


      In this tutorial, you have used Python to convert Markdown text to HTML. You can now write your own Python programs that take advantage of the Markdown syntax in different contexts, such as web applications using a web framework like Flask or Django. For more on how to use Markdown, check out the Markdown website. For more information on using Markdown with Python, check out the Python-Markdown documentation.

      Here are a few extensions officially supported by Python-Markdown:

      • Extra: An extension that adds extra features to the standard Markdown syntax, such as defining abbreviations, adding attributes to various HTML elements, footnotes, tables, and other features.
      • CodeHilite: An extension that adds syntax highlighting to code blocks.
      • Table of Contents: An extension that generates a table of contents from a Markdown document and adds it into the resulting HTML document.

      How To Convert Integers to Floats in Python 3

      Python’s float() method will convert integers to floats. To use this function, add an integer inside of the parentheses:


      In this case, 57 will be converted to 57.0.

      You can also use this with a variable. Let’s declare f as equal to 57, and then print out the new float:

      f = 57



      By using the float() function, we’ve converted an integer to a float.
